[Pure Sine Wave] Converts 12V DC to AC 220V household wall power with continuous 1000Watts output ( 4000Watts surge capability) with 1 AC receptacles, one LED Voltage display, high current DC terminals and two LED work lights.
[Strong and Durable] Aluminum alloy housing provides advanced protection from drops and bumps.
Battery Usage Time Calculation:
1)The working time of inverter, it is depend on the battery power and load power.
2)Formula: Working time (hours)= Battery Capacity X Battery Voltage X 0.8X0.9/Load Power
3) For example, the battery of 12V 60A is supplied to a 220V 100W bulb.
The working time is = 12(V) X 60(AH) X 0.8 X 0.9/100(W)=5.18(hours)
(Note: 0.8 is battery discharge coefficient, 0.9 is inverter conversion efficiency)
